Initial AWS EKS support

[timberio-campfire]

We'd like to officially support Amazon's EKS platform.

1. We should start with a specification to determine the best path forward.

2. Its possible this might just wrap existing sources.

3. Its possible this might just be an installation page in our documentation.

@binarylogic I think this makes sense, do we also want to open a more generic kube issue since I believe the implementation that will work for eks will work for any kube deployment?

[binarylogic]

Yes, #260 handles that.

Current Kubernetes implementation in #893 was tested with AWS EKS ec2 cluster, and it works out of the box. Except of one bug found during testing.

So as @binarylogic said, this will be solved with #260. I anticipate that only retesting it on EKS will be needed.

[LucioFranco]

There is nothing to spec out here. Our current kube implementation covers this. What we will need is deployment guides around kube in general and these can be applied to EKS just like how you might apply it to any other kube cluster. Based on that I think this issue can be closed technically?

I wouldn't close this issue until #1060 is implemented. The reason being that namespace information is necessary on EKS to properly filter out system logs. #893 on it's own isn't capable of doing that on EKS. Although, the number of system logs isn't large, it would still bother users.

[LucioFranco]

@ktff I've updated #1060 to include that additional filter.
